Nigrosin is a mixture of synthetic black dyes (CI 50415, Solvent black 5) made by heating a mixture of nitrobenzene, aniline and aniline hydrochloride in the presence of a copper or iron catalyst. It is used in microbiology.
Nigrosin was so named because of its intense black colour, which is useful for the negative staining of bacteria.
Sorry to dissapoint, but this is not a racist word, and has nothing to do with niggers. Look it up on wikipedia.

<Tyrone recently joined a microbiology lab as an lab-assistant>
Scientist: Tyrone, please pass me the nigrosin.
Tyrone: What you be calling me, you honky ass cracka?! I'll have Al Sharpton and the NAACP come down here and sue your ass!
Scientist: No Tyrone. Nigrosin is a dye used for the negative staining of bacteria.
Tyrone: Oh. My bad.

grebo

West Midlands slang word for rockers, bikers, greasers etc. In the late 1980s it was used by the UK music press to refer to a specific scene centered around the bands Pop Will Eat Itself and Crazyhead. The term never found favour with readers of 'the inkies' (Sounds, Melody Maker and the still extant NME) and was soon dropped. Now often used in predominantly working-class areas of the midlands and the north to mean someone who listens to rock-derived music and/or dresses in a manner that suggests they affiliate themselves with rock music of some kind.

Some grebo passed with Sabbath playing on his stereo.
The Poppies are at no. 17? God, a grebo band in the charts!
They're playing nu-metal now, bloody grebos!
